Housing for a tyre parameter monitoring system, tyre parameter monitoring system and method for mounting a tyre parameter monitoring system to a rim of a wheel

Abstract

A housing ( 4 ) for a tyre parameter monitoring system is provided. The housing ( 4 ) comprises two arms ( 10, 12 ) that are shaped and spaced to provide a clamp-in fitting ( 18 ) for engaging with a valve stem ( 34 ) of a clamp-in type valve ( 30 ) such that the valve stem ( 34 ) of the clamp-in type valve ( 30 ) is pivotably engaged with the housing ( 4 ) and such that the angle between the valve stem ( 34 ) of the clamp-in type valve ( 30 ) and the housing ( 4 ) is variable. The housing ( 4 ) also comprises a snap connection fitting ( 16 ) for engaging a valve stem ( 8 ) of a snap-in type valve ( 6 ). The snap connection fitting ( 16 ) is positioned between the two arms ( 10, 12 ).

 a snap connection fitting for engaging a valve stem of a snap-in type valve, snap connection fitting positioned between and spaced apart from an aperture formed from the mounting plate, the first lateral gusset plate, and the second lateral gusset plate. 
 
     
     
       2. The housing according to  claim 1 , further comprising an upper surface from which the first lateral gusset plate and the second lateral gusset plate protrude,
 wherein the snap connection fitting protrudes from the upper surface of the housing. 
 
     
     
       3. The housing according to  claim 2 , wherein the aperture is sized and shaped such that the valve stem of the snap-in type valve or the valve stem of the clamp-in type valve is insertable through the aperture. 
     
     
       4. The housing according to  claim 3 , wherein the first arcuate rail and the second arcuate rail are configured to engage a bar of the valve stem of the clamp-in type valve such that the valve stem is pivotably engaged with the housing. 
     
     
       5. The housing according to  claim 4 , wherein the snap connection fitting comprises an opening configured to accept a valve stem of a snap-in type valve. 
     
     
       6. The housing according to  claim 5 , wherein the valve stem of the snap-in type valve is attachable to the snap connection fitting by a screw. 
     
     
       7. The housing according to  claim 6 , further comprising a sensor unit configured to monitor a tyre pressure positioned in the housing. 
     
     
       8. A tyre parameter monitoring system comprising:
 a first lateral gusset plate and a second lateral gusset plate configured to provide a clamp-in fitting for engaging with a valve stem of a clamp-in type valve; 
 a mounting plate connecting the first lateral gusset plate and the second lateral gusset plate, the mounting plate extending perpendicularly between the first lateral gusset plate and the second lateral gusset plate; 
 a first arcuate rail and a second arcuate rail disposed on an inner surface of the mounting plate or an inner surface of the first lateral gusset plate and the second lateral gusset plate, the first arcuate rail and the second arcuate rail configured to pivotably engage the valve stem of the clamp-in type valve such that an angle between the valve stem of the clamp-in type valve and the housing is variable; 
 a snap connection fitting for engaging a valve stem of a snap-in type valve, the snap connection fitting positioned between and spaced apart from an aperture formed from the mounting plate the first lateral gusset plate, and the second lateral gusset plate; and 
 the snap-in-type valve, the snap-in type valve comprising a valve stem configured to be secured to the snap connection fitting by a screw. 
 
     
     
       9. A tyre parameter monitoring system comprising:
 a first lateral gusset plate and a second lateral gusset plate configured to provide a clamp-in fitting for engaging with a valve stem of a clamp-in type valve: 
 a mounting plate connecting the first lateral gusset plate and the second lateral gusset plate, the mounting, plate extending perpendicularly between the first lateral gusset plate and the second lateral gusset plate; 
 a first arcuate rail and a second arcuate rail disposed on an inner surface of the mounting plate or an inner surface of the first lateral gusset plate and the second lateral gusset plate, the first arcuate rail and the second arcuate rail configured to pivotably engage the valve stem of the clamp-in type valve such that an angle between the valve stem of the clamp-in type valve and the housing is variable;
